clang-format treats MSVC `__super` keyword like all other keywords adding
a single space after. This change disables this behavior for `__super`.

This prevents unwanted fallout from r296664. Specifically in proto formatting,
this changed:
optional Aaaaaaaa aaaaaaaa = 12 [
(aaa) = aaaa,
(bbbbbbbbbbbbbbbbbbbbbbbbbb) = {
aaaaaaaaaaaaaaaaa: true,
aaaaaaaaaaaaaaaa: true
}
];
Into:
optional Aaaaaaaa aaaaaaaa = 12 [
(aaa) = aaaa,
(bbbbbbbbbbbbbbbbbbbbbbbbbb) =
{aaaaaaaaaaaaaaaaa: true, aaaaaaaaaaaaaaaa: true}
];
Which is considered less readable. Generally, it seems preferable to
format such dict literals as blocks rather than contract them to one
line.

Summary:
@see is special among JSDoc tags in that it is commonly followed by URLs. The JSDoc spec suggests that users should wrap URLs in an additional {@link url...} tag (@see http://usejsdoc.org/tags-see.html), but this is very commonly violated, with @see being followed by a "naked" URL.
This change special cases all JSDoc lines that contain an @see not to be wrapped to account for that.

Summary:
Previously clang-format would not break after any !. However in TypeScript, ! can be used as a post fix operator for non-nullability:
x.foo()!.bar()!;
With this change, clang-format will wrap after the ! if it is likely a post-fix non null operator.

Summary:
`interface` and `type` are pseudo keywords and cause automatic semicolon
insertion when followed by a line break:
interface // gets parsed as a long variable access to "interface"
VeryLongInterfaceName {

With this change, clang-format not longer wraps after `interface` or `type`.

Summary:
This patch makes ContinuationIndenter call breakProtrudingToken only if
NoLineBreak and NoLineBreakInOperand is false.
Previously, clang-format required two runs to converge on the following example with 24 columns:
Note that the second operand shouldn't be splitted according to NoLineBreakInOperand, but the
token breaker doesn't take that into account:
```
func(a, "long long long long", c);
```
After first run:
```
func(a, "long long "
"long long",
c);
```
After second run, where NoLineBreakInOperand is taken into account:
```
func(a,
"long long "
"long long",
c);
```
With the patch, clang-format now obtains in one run:
```
func(a,
"long long long"
"long",
c);
```
which is a better token split overall.

Summary:
This patch makes the namespace comment fixer use the number of unwrapped lines
that a namespace spans to detect it that namespace is short, thus not needing
end comments to be added.
This is needed to ensure clang-format is idempotent. Previously, a short namespace
was detected by the original source code lines. This has the effect of requiring two
runs for this example:
```
namespace { class A; }
```
after first run:
```
namespace {
class A;
}
```
after second run:
```
namespace {
class A;
} // namespace
```

Many things were wrong:
- We didn't always allow wrapping after "as", which can be necessary.
- We used to Undestand the identifier after "as" as a start of a name.
- We didn't properly parse the structure of the expression with "as"
having the precedence of relational operators

Async arrow functions should be marked with a whitespace after the async keyword, before the parameter list:

Before:
x = async() => foo();
This makes it easier to tell apart an async arrow function from a call to a function called async.

r289428 added a separate language kind for Objective-C, but kept many
"Language == LK_Cpp" checks untouched. This introduced a "IsCpp()"
method that returns true for both C++ and Objective-C++, and replaces
all comparisons of Language with LK_Cpp with calls to this new method.
Also add a lot more test coverge for formatting things in LK_ObjC mode,
by having FormatTest's verifyFormat() test for LK_ObjC everything that's
being tested for LK_Cpp at the moment.
Fixes PR32060 and many other things.

Specifically, similar to other blocks, clang-format now wraps both
after "${" and before the corresponding "}", if the contained
expression spans multiple lines.
llvm-svn: 295663
Before:
var someValue = (v as aaaaaaaaaaaaaaaaaaaa<T>[
]).someFunction(aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa);
After:
var someValue = (v as aaaaaaaaaaaaaaaaaaaa<T>[])

This can lead to bad behavior with macros that are used to annotate
functions (e.g. ALWAYS_INLINE).
Before, this:
ALWAYS_INLINE ::std::string getName() ...
was turned into:
ALWAYS_INLINE::std::string getName() ...
If it turns out that clang-format is failing to clean up a lot of the
existing spaces now, we can add more analyses of the identifier. It
should not currently. Cases where clang-format breaks nested name
specifiers should be fine as clang-format wraps after the "::". Thus, a
line getting longer and then shorter again should lead to the same
original code.
